Exchanging Periods and Commas in Numbers
To exchange the periods and commas used for the decimal point and
digit separators in a number:
1. Press
D
to access the DSP (display) menu.
2. Specify the decimal point by pressing  or . Pressing
 sets a period as the decimal point and comma as the digit
separator (U.S. mode). (For example, 1,000,000.00.) Pressing
 sets a comma as the decimal point and period as the digit
separator (non-U.S. mode). (For example, 1.000.000,00.)
